oWATER-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 519,040, dated May 1,1894. I

Application filed October 25,1893.

To alt whom it may concern:

-1 3e If. known that I, ARTHUR G. GLASGOW, a citlzen of theUnitedStates, residing in Lonvdon,in the countyof Middlesex, England,have lnvented a certain new and useful Improvement n Tater-GasApparatus, of which the following 1s a true description, reference beinghad to the accompanying drawings, which form a part hereof. i

My invention relates to Water gas apparatus, particularly to suchapparatus as are provided with suitable conduits leading from above andbelow the grate, or other support, for the mass of incandescent carbonwhich serves to decompose the steam and form water gas so that the gascan be made both upand down; and the main object of the invention- 1s toso arrange the openings of'these two conduits into a common conduit thatthe hot gases issuing from one conduit will not im p nge on the openingof the other and pro vlde a common valve to close alternately both ofthese openings My invention will be best understood as explained inconnection with the accompanying drawings, in which Figure 1 is a sideelevation partly in sect on of an apparatus embodying my inven- 131011.Fig. 2 is a plan view partly in section on the line m-a: of Fig. 1.Fig.3 is a view partly in section on the line 'y y of Fig. 1. Flg. 4 isa view similarto that shown in Fig. 1, showing a modified form of gasvalve, and Fig. 5 is a view illustrating another form of gas valves.

Ais a water gas generator having a cap B and a grate or other suitablesupport for the fuel as indicated at a.

G G are passages for the gas situated re-' spectively near the top andbottom of the generator, that is, above and below the grate or supporta.

D D are gas conduits leading from the passages O C and open into acommon conduit E; as-shown, their openings 01 d are close together sothat a single valve H can be operated so as to alternately close theopenings. Any suitable means can be employed to actuate the valve H.

meshes with the teeth of a rack h on the valve H which in this case is aslide valve; by turning the hand Wheel J the valve may thus be slid tocover either the opening (2 or d and thus permit the gas drivenfrom thegenerator by the steam blast to escape by means of either one of theconduits D or D as preferred.

In Fig. 4 the valve H is shown as a swing valve pivoted as at h audprovided with seating faces h h, on its front and back which are adaptedto seat on the valve seats at d and d and so close one or the other ofthe conduits; this valve is shown operated by means of a handle or leverj having a rod j connectedtherewith which is secured to rock shaft 72.secured to the valve. In Fig. 5 a s'imilar'lever is shown operating arocking cylinder valve pivoted at h It is evident that any constructionof suitable valves may be employed to close alternately one or the otherof the conduits D D. A construction including pivoted valves is notspecifically claimed in this application but is made the subject ofanother application for Letters Patent, filed- October 25, 1893, andserially numbered 489,111.

G is a steam pipe leading from any suitable boiler a suitable valve (notshown) be ing of course arranged in the pipe whereby the steam can beturned into or off from the pipe; and-the pipe G is provided with twobranches G G leadingto the top and bottom of the generator respectively;a valve 9 is arranged to direct the steam from the pipe G into one orthe other of the branches G G Inorder to .operate this valve to properlydirect the steam blast in accordance as the upper or lower conduit D orD is open I preferably connect the steam valve with'the means foroperating the gas valve so that both can be moved at one operation; thiscan be done in any convenient manner. In Figs. 1' and 2 a small gear 9on the stem of the valve g meshes with a gear g on the shaft I of pinionI and is adapted rtocope'rate the valve 9 so as to direct the steam intobranches G or G as the valve His slid so as to cover the openings 01 orcl; in Figs. 4 and5 the valve g is shown with a projecting rod g whichis loosely held between two lugs 9' on the rod j and serves to operatethe valve 9 as the rod j is moved up and down to operate the valve H. Inoperation the valve His so turned as to open the conduit D leadingfromthe upper part of the generator, a fire is kindled on the grate a, asuitable blast is introduced and a deep bed of incandescent fuel is thusobtained, the blast gases escaping out the conduits D and E and servewhen ignited by a suitable air blast in the carbureter F to heat this inthe customary manner.

It will be observed that the valve H in each of the constructions is soarranged that it will be entirely out of the way of the intensely hotblast gases; the swing valve shown in Fig. 4; is adapted, when swunginto the position indicated by the dotted lines, to be flush with thefloor e of conduit E so that the hot gases will flow over the valve andwill not impinge directly on any part of it; the same is true of thevalve shown in Fig. 5. In the arrangement shown in Fig. 1 the conduit Eis preferably provided with an extension E, the conduit D openingdirectly into the conduit E and the conduit D into the extension E, theopenings (1 d of said conduits being side by side as shown, whenblasting, the valve is slid to cover the opening cl and is moved backinto the extension E entirely out of the path of the blast gases therack and pinion being beneath the disk, no dust or cinder, blownforward, canEinterfere with its working. After the blast has been shutoil the gas valve is moved to open the conduit D or D as maybe desired,and steam is turned into the pipe G the steam being turned into theopposite end of the generator from that from which the open conduitleads.

If desired, the gas valve shown in Fig. 8 can be clamped in the positionshown by means of a screw M to prevent any tendency toward leaking, andas best shown in this figure, the valve is preferably provided with atoothed tail piece I-I forming a continuation of the rack 77. which tailpiece is comparativelythin so that it will not interfere with the draftof gas through the conduit D but will serve to mesh with the teeth onthe pinion when the valve is in its forward position covering theconduit D; the pinion I and this comparatively narrow rack are entirelyin the conduit D'leading from the bottom of the generator, and so arenever subject to the intense heat of the blast gases, and are at alltimesfree from the dust and cinders blown forward during blasting.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, isy 1. In awater gas apparatus the combinationwith a generator having gas passages at its top and bottom, of separateconduits D D leading from said passages, a common conduit E into whichthe conduitsD D open, the openings cl d of the conduits D D'iiuto theconduit E being out of line with each other, a common valve arranged inconduit E to alternately close one or the other of the openings cl and dof the conduits D and D and means for operating said valve, allsubstantially as specified and so that when closing either of theopenings said valve Wlll be out of the path of the hot gases issuingfrom the other.

2. In a water gas apparatus the comb1nat1on with a generator having gaspassages at its top and bottom, of separate conduits D D leading fromsaid passages, a common conduit E into which the conduitsD D open, theopenings d d of the conduits D D into the conduit E being out of linewith each other, a common valve arranged in conduit E toalternatelyclose one or the other of the openings d and d of theconduits D and D, a steam pipe G having branches G and G leading to thetop and bottom of the generator respectively, a valve adapted to directthe steam from pipeG into one or :the other of the branches G or G andmeans for operatin g the valve in conduit E and the steam valve at oneoperation, all substantially as specified and so that when closingeither of the openings said valve will be out of the paths of the hotgases issuing from the other.
